Tweeting the Headache Meetings: Cross-Sectional Analysis of Twitter Activity Surrounding American Headache Society Conferences.

OBJECTIVES: To describe and analyze Twitter activity associated with American Headache Society (AHS) conferences and evaluate the potential for Twitter to promote education and public outreach. BACKGROUND: Many medical and scientific conferences have adopted Twitter as a method of promoting discussion among attendees as well as increasing visibility. Relatively little is known, however, about the composition of conference Twitter activity, the participants, and the impact on broader Twitter discussions. METHODS: We analyzed Twitter data from 5 AHS conferences held from 2014 to 2016 using their respective hashtags. Using the Symplur Healthcare Hashtags open social media search platform, we gathered data on numbers of tweets, impressions, participants, and mentions during a 10-day period surrounding each conference, as well as samples of Twitter accounts participating. Prominent accounts were categorized as individual medical professionals, other individuals, host organizations, health-related organizations, medical centers, and industry by cross-checking their Twitter profiles and conference registration lists. Larger samples of accounts participating in the 2016 conferences were also obtained and categorized similarly, with individual person accounts classified by conference registration status. A related prominent hashtag (#migraine) was also identified and Twitter usage before, during, and after each conference was analyzed to evaluate the impact of conference activity on broader Twitter conversations. RESULTS: Nineteen thousand nine hundred thirty-six tweets were generated across the 5 conferences, with 11,531 (58%) created by the Top 10 participating accounts in each conference, which were primarily individual medical professionals and host organizations. Thirty-two million six hundred eighty-three thousand impressions were generated across the 5 conferences, with 24,656,000 (75%) coming from the Top 10 participants in each, particularly host organizations and other individuals. An average of 331 accounts participated in each conference. The Top 10 mentioned accounts in each conference (consisting of 21 unique accounts with 14 accounts in the Top 10 across multiple conferences, primarily individual medical professionals) received a total of 15,093 mentions. Among 135 unique accounts participating actively in the two 2016 conferences, 39% were individual medical professionals, 38% other individuals, 16% health-related organizations (including the 2 host organizations), 4% medical centers, and 2% industry. From these samples, 34 of 70 (49%) and 43 of 66 (65%) individual person accounts participating in the Twitter discussion at each conference were not registered conference attendees, indicating substantial outside participation via Twitter. #migraine usage during conferences showed a significant increase from baseline in number of tweets (6080 in a 10-day period vs 3721, P < .0001) and participants (2332 vs 1830, P < .0001) but the increase was not significant for impressions (30,155 vs 25,361, P = .240). CONCLUSIONS: Consistent with the dynamics of Twitter conversations on other topics, AHS conference discussions featured a small group of accounts creating the bulk of content, with individual medical professionals and host organizations generating the largest shares of tweets and mentions while host organizations and other individuals produced the most impressions. Participating accounts were mainly individuals and health-related organizations, with more non-attendee participants than expected. Conference Twitter activity correlated with a significant increase in #migraine usage, suggesting a perceptible influence on the discussion of health-related topics beyond the conference itself.

Outpatient Motor Retraining for Functional Movement Disorder: Predictors of a Favorable Short-Term Response.

Background: Treating functional movement disorder (FMD) with motor retraining is effective but resource intensive. Objectives: Identify patient, disease, and program variables associated with favorable treatment outcomes. Methods: Retrospective review of the 1 week intensive outpatient FMD program at Mayo Clinic in Minnesota from February 2019 to August 2021. Outcomes included patient-reported measures (Canadian Occupational Performance Measure-Performance and Satisfaction subscales [COPM-P and COPM-S, range 0-10] and Global Rating of Change [GROC, -7 to +7]) and a retrospective investigator-rated scale (0-3, worse/not improved to significantly improved/resolved). Linear regression models identified variables predicting favorable outcomes. Results: Participants (n = 201, 74% female, mean age = 46) had median FMD duration of 24 months. The commonest FMD subtypes were gait disorder (65%), tremor (41%) and weakness (17%); 53% had ≥2 subtypes. Most patients (88%) completed a therapeutic screening process before program entry. Patient-reported outcomes at the end of the week improved substantially (COPM-P average change 3.8 ± 1.9; GROC post-program average 5.5 ± 1.7). Available investigator-rated outcomes from short-term follow-up were also positive (102/122 [84%] moderately to significantly improved/resolved). Factors predicting greater improvement in COPM-P were completing therapeutic screening, higher number of non-motor symptoms, shorter FMD duration, earlier program entry, lower baseline COPM scores, and (among screened patients) higher GROC between therapeutic screening and program start. Conclusion: Patients with diverse FMD subtypes improved substantially over a 1 week period. Utilization of therapeutic screening and greater improvement between therapeutic screening and program start were novel predictors of favorable outcomes. Non-motor symptoms did not preclude positive responses, although patients with predominant non-motor burden were excluded.

In Patients With Functional Movement Disorders, Is Specialized Physical Therapy Effective in Improving Motor Symptoms?: A Critically Appraised Topic.

BACKGROUND: Functional movement disorders (FMD, aka psychogenic movement disorders) are very common and frequently chronic and disabling. Despite this, there is a paucity of evidence-based treatment to manage and alleviate these conditions. Specialized physical therapy (PT), involving sequential motor relearning and redirecting attention, has shown promise as a therapeutic intervention for motor symptoms. METHODS: The objective of this study was to critically assess current evidence regarding specialized PT compared with usual care in improving motor symptoms among patients with FMD. This was addressed through the development of a structured critically appraised topic. This included a clinical scenario with a clinical question, literature search strategy, critical appraisal, results, evidence summary, commentary, and bottom-line conclusions. Participants included consultant and resident neurologists, a medical librarian, and content experts in the fields of physical medicine and rehabilitation, physical and occupational therapy, psychiatry, and psychology. RESULTS: A randomized controlled feasibility trial was identified and selected for critical appraisal. This study randomized 60 patients with FMD to a 5-day specialized outpatient PT program or to general outpatient PT referral, and measured patient-reported and clinician-measured outcomes. At 6 months, 72% of patients in the intervention group had a good outcome compared with 18% of control group patients. Patients in the specialized outpatient PT program had significantly better outcomes in 3 Short-Form 36 (SF36) domains (d=0.46 to 0.79) and multiple other scales of physical and social function as well as clinician-measured outcomes. The intervention resulted in 0.08 additional quality-adjusted life years in a cost-effective manner. CONCLUSIONS: Current evidence suggests that in patients with FMD, specialized PT improves motor symptoms in a clinically significant, sustained, and cost-effective manner. This promising intervention warrants further investigation and replication.
